RAILWAY-CROSSING.

Substitute for application SerialNo. 49,941,

To all whom it may concern:

Be it known that I, LANGELOT RYAN, a citizen of the United States, and a resident of the city of St. Louis, in the State of Missouri, have invented a new and Improved Railway-Crossing, of which the following is a full, clear, and exact description.

My invention relates to railway crossings, particularly crossin s of street railways, and has for its prime 0 ject the purpose of reducing the pounding and jar incident to the use of crossings as ordinarily constructed.

In the ordinary crossing, the bumping or pounding is caused by the car wheel jumping across the car groove formed in the crossing track for the fiangeof a wheel traveling on the other track. In my invention I provide an elevation at the distant side ofthe flange groove and a bevel or -incli ne leading to said elevation, the arrangement being such that before the tread of a crossing wheel leaves the rail at one.

side of a groove, the tread of the wheel at a forward point thereon will contact Withthe incline leading to the elevated tread surface of the track. Thus, the pounding. of the car wheel against the track surface at the opposite side of the groove is reduced to a.

minimum.

The invention will be ,particularly explained in the specific description followmg:

Reference is bad to the accompanying drawings forming part of this specification, in which similar characters of reference indicate corresponding parts inall the views, and in which: 4

ig. 2 is a detail CIOSSTSBOtlOIl of a rail, giving the preferred form of the rails at the crossing;

Fig. 3 is a longitudinal vertical section on the line 33 of Fig. 1; and

Fig. 4 is a perspective view of the crossing, the tread members of the rails being omitted except at one corner of the crossm in constructing a practical embodiment of my invention, the rails at the crossing are preferably composed of a base section 10 presenting flanges and a web, and said base section receives a tread section 11 havin Specification of Letters Patent.

bolts 13 and nuts 14. Thus the crossing will be composed of a permanent base presenting flanges and vertical webs, together with removable quarter sections, see Fig. 2, and the lower right hand corner of the crossing, Fig. 4. The construction permits of the renewal of a particular quarter section when worn,

w1thout renewing the, base structure, and,

is applicable to crossings generally of steam railways and street railways.- The crossing,

in the tread surfaces of the rails, will present grooves 15 for the flanges of a car wheel.

I have designated the rails of one track generally by the letter A and the crossing tracks by the letter B, and in Fig. 3 have indicated car wheels C. Referring, particuv larly'to Figs. 1 and 3, it is to be assumed in these figures that cars travel in the direction of the arrows on the tread surfaces a, b, of the tracks (Fig. 1) and in the direction of the arrow in Fig. 3. The tread surfaces a areat the regular height of the tread surfaces of the railsgenerally throughout the tracks, and I providein that rail at the left of the track, that is, at the lower side of Fig. Let the opposite side of the first groove 15 to be crossed, arise or incline a which leads to an elevatedportion of the tread surface. At the right of Fig. 3 it will be seen that before the wheel O leaves the regular level a, a forward part of the tread surface of the wheel C will have contacted with the incline a Hence there will be a minimum pounding of the wheel in passing from the surface a to the incline a -'Ihe track will gradually lower from the elevated portion adjacent to the incline a as indicated in Fig. 3 until the re lar level a is again sc ribed with reference to the surfaces a.

since the surfaces-fa, b, to the in 'conditions are similar clincs a, are on the same level the surface incline 5 will start and at elevations corresponding to the start and terminal oi? the incline (4 At the lower left hand corner of Fig. 1, however it is to he observed that a Wheel in crossing from to the incline Za" at the opposite side of a groove 15, will first travel over the incline (1. in the rail A and hence will travel from a elevated portion of the rail A to th inclination L 'lheretore, the incline (5 starts at an elevation corresponding with the highest portion of the incline a and rises to a higher elevation in the track B, Thus the incline (i rises from the regular level a and the incline Zi rises to a higher elevation than the incline 11F. Assumh'ig; that in practice there will be a rise of, 3301' example one-tenth of an inch at the incline and a further rise or" one-tenth of an inch at the incline there will he's total rise of two-tenths from the regular track level at the incline if.

l'lolerring HOW to the uipei' right hand corner of Fig, 1, it Will be seen that the to the lower left hand corner. Thus a Wheel traveling from the surface Zi to the incline 5 will be carried upwardly from said incline. Hence the incline o in the rail A, adjacent to the incline Z7 will rise relative y to said incline J, the relation between 5 and being the line as with respect to the inclines (L23 7/. in the upper lei't hand corner of Fig 1. it will be seen that conditions are such above the regular tracl; level, The inclnies a 6* meet in a initer line in all cases it will be seen that the incline is at the far side of a groove to be crossed hjfl the tread of a wheel and in all cases the incline will rise relatively to the level at the near side of the groove.

Having thus described my invention, What 1 claim as new and desire to secureby Letters Patent is: i i

1. A railway crossing, the'rails of which present grooves at their intersections for the passageof wheel flanges, and present, in the tread of each crossing rail, at the far side of a groove, a surface elevated above the tread surface at the near sicleof the groove, there being inclines at said far sides of the grooves, leading from the said grooves to said elevated surfaces and adapted to receive the contact of a wheel tread before the tread leaves the rail surfaces at thence-r sides of the grooves.

2. A railway crossing, the rails which present grooves at their intersections for the passage of Wheel flanges, and present, in the tread of each crossing rail, at the far side of a groove a surface elevated above the tread surface at tie near side of the" grooves to said elevated surfaces and adapted to receive the contact of a. wheel tread before the tread leaves the rail surfaces at the near sides of the grooves, the acent ele (l surfaces and the respective inclines oi? the crossing rails being at the same elevation at certain corners of the crossing and at other corners of the crossing the inclines and elevated surfaces of one rail being higher than the adjacent inclines and eleated surfaces.
